Le'tIeIS Patent No. 108,678, dated October 25, 1870.

IMPROVEMENT IN MACHINES FOR FINISHING HEELS ON BOOTS AND SHOES.

m The Schedule referred to in these Letters Patent and lmaking part of the same.

To all whom it may concern.:

Beit known that I, HORACE H. BrGELow, of the city and county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Machines for Finishing Heels on Boots and Shoes and I do hereby-declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing which forms a part ofthis specification, in which* Figurel represents a perspective view of my improved machine for finishing heels;

Figure 2 represents an end view of the same, supporting standards not shown;

Figure 3 represents "an end view with the finishing-wheel removed to show the interior;

Figure 4 represents a central longitudinal section 5 and Figure 5 represents a transverse section.

lo enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it more in detail. y

The nature of my invention consists in a heel-dnishing machine, the parts of which are constructed and combined as hereinafter describe( My improved machine' for finishing heels is con-- structed as follows The main shaft,'indicated by A in the drawing, is mounted upon and arranged to turn in the bearings a a at the upper ends of the supporti-ng standards A l Upon each end of thc shaft A is arranged a finishing-wheel, B, the outer side of which is coated with cmcry.

The wheels B B are held upon thel shaft A by means of nuts b I), which screw onto the ends of the shaft outside the wheels. The nuts can be easily taken oit when it is desirable to remove the wheels from the shaft for any purpose.

A fan-wheel,- C, is attached to .the central part of the shaft A, and it is also provided with a suitable driving-pulley, D.

The working portions ot' the machine are inclosed in metalliccasiugs E EVE?, the upper portions of which are joined so as to form a continuous casing the fullvlength of lthe machine, while at the lower side it is divided into sections, as shown `in thedrawiug,.the portions E being curved upward at the un-v der side', so that they do not inclose the main shaft A and driving-pulley DT The lower portion of the casing El, which surf rounds the fan-wheel, is extended to the rear, as shown at F, and provided with a suitable opening for the'exit of the air from the fans C.

Suitable openings Gr G are formed through the sides of the casings E E1 Ez into the divisions E, as indicated, to permit the passage of air to the fanvwheel C.

Doors II are arranged in the easings E\E2, outside the emcry-wheel B. Said doors are hinged to the rear of this casing, as indicated at I, and are provided with latches J at their front sides for keeping them closed.

An opening is formed iu the center of the doors H, to allow space for the nut b, while a second opening,

K, is formed near their front edges, through which wheel B, which grinds olf` they rough ends of the y nails and uneven portions of the lifting in a very rapid and effective manner, the action of the emery leaving their surface in such condition that the heels can be quickly smoothed by their application to the sand-paper wheel.

It will be observed that' by the use of my improved machine, the slow and laborious process of tiling the heels is superseded and much time and label' saved,

and the operation of finishing the heels greatly facilitated, while the work is done in a more thorough and satisfactory manner. 4

By making the machine with two finishing-wheels, it enables two operatives to work at the 'machine at thesalne time.

All dust and dirt occasioned by the tiling or grinding of the heels are drawn into the casing through the space around the edge of the wheels B, and the openings G G', by thefaction of the fan-Wheel C;

and thereby dischargedthrough the rear exit-branch' F, from which a conductor may extend to the outside of the building, or into any suitable receiver.

rlhe heels may be introduced to the wheels B through the openings K, or, provided the operators be experts in the art of grinding, the doors may be swung back, so asv to expose the whole side ofthe wheels.

Having described my improved machine for finishing heels on boots and slices, -f

What I claim therein as new, and -of my invention, and desire to secure hy Letters Patent, is-

1. The arrangement of the shaftAand the fanwheeland finishing emery-wheels, mounted on the same, and the casing constructed-to cover and surround said fan and emery-wheels without iuclosing the said shaft, a's herein shown and described.

2. The arrangement in the ends of, the casing and opposite the emery-wheels of the doors vH, provided with openings K, substantially as and for the purposes shown and set forth.
